T 0 all w'iom 'it may concern Be it known that We, Pin'rno Ciinmnnniir and Armenio Miincicni, subjects of the King of italy, residing at Utica, in the county of neida and State of New York, have invented new and useful .improvements in Rail-Joints, of which the following is a speciliration.

The present invention relates lo rail joints, and the primary object ot the saine to provide a. rail joint whereby the rails may be easily and securely connected and further whereby neither of the rails will he restricted in its longitudinal movement incident to the expansion and contraction ot the rails due to temperature changes.

further object of the invention is to provide rails having lapping ends with fish plates for connecting the ends and to arrange the said fish plates so that the rails may contract or expand without influencing the connecting plates.

lilith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts set forth in the following specification and ialling within the scope of the appended claim. l, in the drawing: .Figure 1 is a side elevation of tivo rails constructed in accordance with the present invention. Fig-2 is a horizontal sectional' view on the line of Fig. l, and Fig, 3 is a transverse sectional View on the line 3-3 ot Fig. 1. Fig. 4 is ar'detail perspectire vieu- @t the bolt.

In the drawings, the rails are indicated by the characters lil-ll," and the body ot each of said rails` is of the ordinary coiistruction lach ot the rails, at its ends, and upon one 'of itseides, piaivided with integrally' Vformed cxtensions'm the natureof plates llf `'The plates ha '-:e their inner faces arranged in adino with one of the sides of the wehgit each of thc rails, and

are ot width ciuialing the distance between the head and base tlaiioe ot' the rail. .vhile the edges of the plates conform to the shape of the upper faces of the base ianges ot the nils. Y

The vertical plato upon the rail R is designated by the numeral Q, and the vertical plate projecting beyond the. end ot' tbc rail R" is indicated by the immoral The lWebs of the said rails are enlarged or thick4 cned for a considerable distance rein their ends proper, and these enlarged or thickened portions, -ivlnci may he designated by the numerals 4 and 5 respectively are formed with transversely arranged elongated openings 6 and? respectively, two of the openings t3 being provided in the rail R, and a siinilarinumber 1loeing provided in the enlarged portion ot' 'the rail R. rlie plates Q and S-are also provided with elongated openings 8 and 9 respectively, corresponding in number and size With the openings 6 and 7, and these openings are adapted to aline when the rail ends abut. Upon the enlarged portion and plate :2 of the rail R we employ tvvo bars or plates 10 and 11 respectively, each of the plates being provided with a pair ot' round openings 12- and 13. These openings are adapted to communicate cent-rally with the elongated openings above mentioned, and upon the outer face of the plate 3 andthe enlarged portion of the rail R, ive provide two similar plates 14. These plates are each provided with a pair of elongated openings 1G and 17 respectively. The openings 1G and 17 may he of a length corresponding with the length of the elongated openings in the rails and their angular extensions or may be of a lesser Width it desired. rlhe openings 16 and 17 are adapted to snugly receive the loclringshoiilders 18 which are arranged upon the heads 19 of bolts 20. 'T he shoulders do not extend through the openings 16 and 17, that is, they do not project to within the elongated opeir ings formed in the enlarged portions oit' the shoulders and the vertical extensions of the angle members of the rails, so that only the rounded Shanks of the said bolts pass through the elongated 'openings and through the round openings 12 and 13 in the plates 10 and 11. Nuts 21 are employed upon the extending ends of the'holts. The nuts onlybind sui'hciently against the plates 10 `and breakage vot the rails at the joints because no provision nas inade for the free expanl sion and contraction .of the rails at this This is a feature greatly deiy sued, as disasters have resulted from the point, and Lt'uithen-:tcr the reason thatforeignv matter has been permitted to enter the bolt' openings which serves as an obstruction or as a means for halting the longitudinal movement of the rails ends, and as a consequence, causing the breakage of the rails at the joints. It will also be noted that the arrangement of the plates is such as to permit of' the rail ends moving longitudinally from or toward each other Without engaging the plates.

From the above description, taken in eonnection with the accompanying drawings, the simplicity of the device as Well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such inventions appertain Without further detailed description.

Having thus described the what we claim is:

The combination with two rails having invention,

lapped ends and provided with elongated bolt openings, plates arranged in pairs on the opposite sides of the rails and at the ends thereof, the plates on one side of the rails having elongated openings correspond ing to and registering with the elongated openings in the rail ends, the plates on the opposite sides of the rails having. round openings which are arranged centrally of the elongated openings in the rail ends, shouldered bolts passing through the open ings, the said bolts having their shoulders
